PCT No. PCT/EP82/00092 Sec. 371 Date Dec. 13, 1982 Sec. 102(e) Date Dec. 13, 1982 PCT Filed May 4, 1982 PCT Pub. No. WO82/03985 PCT Pub. Date Nov. 25, 1982.Multistage process for permanent shaping of hair, whereby the hair is at first treated with a liquid hair keratine reducing permanent shaping agent before and/or after rolling the hair onto rollers. This liquid, weak shaping effective permanent shaping medium is able to shape the hair in the area of the hair tips without damaging the hair tips during the reaction time. Subsequently, a consistent keratine reducing permanent shaping medium is applied to the rolled up hair which has a viscosity of 50 to 5000 m Paxs, preferably 100 to 500 m Paxs at a temperature of 30 DEG C. and which has a stronger shaping effectiveness with respect to the liquid permanent shaping medium. The consistent permanent shaping medium screens the hair to the outside and prevents the access of atmospheric oxygen, on the one hand, and the escaping of a volatile alkalization agent like, for example, ammonia, on the other hand. Furthermore, due to the higher shaping effectiveness of the consistent permanent shaping medium a good shaping of the beginning of the hair is obtained without the danger of an excess curling of the tips of the hair. After a sufficient reaction time, the hair is rinsed and is then treated with an oxidating effective solution.
